Learn PowerPoint 2010: Internal Margins for Text Boxes

Internal margins are relevant to all the three types of text containers in PowerPoint — these three containers are text boxes, text placeholders, and shapes that contain text. Internal margins control the amount of blank space between the perimeter (edge) and the actual text within the text container. Although these margins are similar to the margins of pages in a word-processing document like Microsoft Word, there is a significant difference. Each text container has its own individual margins set, and you can have entirely different margins for one or more text containers, even if they reside on the same slide.
